Overview
The BYG22A-E3/TR is a fast recovery avalanche rectifier diode manufactured by Vishay General Semiconductor. It features a peak repetitive reverse voltage of 200 V and a maximum continuous forward current of 2 A. The device exhibits a typical peak reverse recovery time of 25 ns, making it suitable for high-frequency applications. Packaged in the surface-mount DO-214AC (SMA) case with two pins, it operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum non-repetitive peak forward surge current of 35 A and a low reverse leakage current of 10 μA.
Feature Summary
- Engineered with avalanche rated capability for robust operation under transient conditions
- Fast recovery design minimizes switching losses and reverse recovery charge
- Utilizes glass passivation to ensure stability and reliability across wide temperature ranges
Applications
- High frequency switching power supplies
- Free wheeling rectification in DC-DC converters
- Snubber circuits in inductive load protection
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm package type and tape-and-reel specifications. Ensure the component meets required automotive or industrial standards if applicable. Cross-reference datasheet parameters such as thermal resistance and maximum ratings with system requirements before finalizing procurement decisions.
Selection Notes
Select this component when a surface-mount solution is required for high-speed rectification at 200 V. Compare its 25 ns recovery time against standard rectifiers to evaluate efficiency gains in high-frequency topologies. Consider the DO-214AC footprint constraints and thermal management capabilities relative to the 2 A continuous current rating.
Part Context
This part belongs to the BYG series of fast recovery rectifiers from Vishay. These components are designed for general-purpose high-efficiency applications requiring fast switching speeds. The series offers various voltage ratings and current capacities in compact surface-mount packages to support modern PCB density requirements.
Replacement Considerations
Consult official Vishay substitution guides for verified equivalents. Generic replacements may differ in avalanche ruggedness or reverse recovery characteristics.
